Fuel Gauge The fuel gauge The fuel gauge displays approximately how much fuel is in the fuel tank only when the ignition switch is ON. For proper fuel gauge indication after adding fuel, turn the ignition switch OFF while refueling the vehicle. The fuel gauge indicator may vary slightly when the vehicle is in motion. The most accurate reading is obtained with the vehicle on level ground. With ignition switch OFF, the fuel gauge indicator may drift from the ignition switch ON position. Engine Coolant Temperature Gauge This gauge indicates the temperature of the engine coolant, not the coolant level. If the coolant is not at its proper level or mixture, the gauge indication will not be accurate. The pointer moves from the C (cold) mark into the NORMAL band as your engine coolant warms up. Under normal driving conditions, the pointer should stay in the NORMAL band. It is acceptable for the pointer to fluctuate within the NORMAL band under normal driving 58
